Advice on the entire breadth of business concerns in environmental matters is offered by the team at Mattos Filho
, which is always primed to assist with climate change strategies and transactions, administrative and judicial litigation, negotiations with regulatory agencies and prosecutors, as well as capital markets and finance transactions with sensitive environmental elements. Green financing, the circular economy, brownfields, contaminated sites, and the rights of traditional and indigenous communities count among the recognised competencies of the practice. In Rio de Janeiro, Antonio Augusto Reis is a key contact for litigation, M&A, financing, project structuring, and licensing, and Rômulo Sampaio couples climate change and socio-environmental impact expertise with an in-depth understanding of carbon markets, waste management, and water resources. Dedicated ESG specialist Juliana Ramalho assists with crisis management, investigations, and administrative proceedings from her seat in São Paulo. Associates of note in São Paulo include: Igor Lyra, who specialises in consensual conflict resolution involving government, enterprises, traditional communities, and cultural historical heritage; Tábata Boccanera Guerra de Oliveira, who focuses on licensing processes, climate change matters, and project financing; Marina Montes Bastos, who excels in biodiversity, solid waste, contaminated areas, and water resources; and Bruna Araujo Ozanan, who fields extensive environmental litigation experience.
